The Raman Research Institute was founded in 1948 by the Indian physicist and Nobel laureate, Sir CV Raman, to continue his studies and basic research after he retired from the Indian Institute of Science. The Raman Research Institute is now an autonomous research institute engaged in research in basic sciences. Today, the main areas of research at the Institute are Astronomy & Astrophysics, Light & Matter Physics, Soft Condensed Matter and Theoretical Physics. The research activities include work in Chemistry, Liquid Crystals, Physics in Biology, and Signal Processing, Imaging & Instrumentation.
Area of Research
Astronomy and Astrophysics
Members of the Astronomy and Astrophysics Group are currently engaged in research into the understanding of events in the evolving universe and a variety of phenomena associated with cosmic bodies: the evolution in the gas during the epoch of re-ionization, the nature and composition of the gaseous medium in galaxies at high redshifts, in clusters of galaxies at high redshift, in galaxy groups, in galaxies – normal, active and low-surface-brightness galaxies – in the present era. The phenomenological studies target the enigmatic and amazingly energetic gamma ray bursts, giant pulses from pulsars, recurrent active galaxies, X-ray binaries, hydroxyl and methanol maser sites and sources, and photon-dominated regions of the interstellar medium. Theoretical advances include understanding of specialised issues like strong MHD turbulence, the interaction between galaxies and their environments, the role of the Pancharatnam phase in certain optics arrangements, and unsolved problems associated with neutron stars, magnetars, and strange stars.
The telescopes and receivers developed and built in the Electronics Laboratory provide vital observational clues for this research. However, the Institute’s facilities cover only a part of the electromagnetic spectrum. A holistic investigation of space phenomena often requires observing capabilities not available in India, therefore, the astronomers of the Institute propose and successfully win the use of valuable observing time on facilities across the world.
Light and Matter Physics
The Light And Matter Physics (LAMP) Group at RRI is engaged in an area of light-matter interaction which is a combination of Atomic, Molecular and Optical (AMO) physics on one hand, and intense laser field studies of plasmas on the other.
The AMO activities involve studying, manipulating and understanding cold atomic, molecular, and ionic matter. Ultra-cold dilute samples of such forms of matter provide an excellent testing ground for studies into the fundamental quantum nature of matter. Of special interest is the building of Quantum Logical Gates by tailoring their internal degrees of freedom in external potentials.
